Out of the box, ANAVI Macro Pad 10, ANAVI Knobs 3 and ANAVI Knob 1 are all powered by the open source KMK firmware written in CircuitPython. However, probably the most popular open source firmware for mechanical keyboards is QMK.

QMK stands for Quantum Mechanical Keyboard and it is an open source community centered around developing various computer input devices. The project is hosted in GitHub. More than 1800 developers have contributed to this open source firmware over the years. QMK supports more than 2000 keyboards and keypads brands. It has an excellent documentation and various convenient tools to modify and create your own custom keyboard layouts.

In September, QMK added initial support for the Raspberry Pi RP2040 microcontroller. October is Hacktoberfest, a month-long celebration of open-source projects, so this is a great opportunity to port QMK to [ANAVI Macro Pad 10].(https://github.com/qmk/qmk_firmware/pull/18620), ANAVI Knobs 3 and ANAVI Knob 1. This is still work in progress. There are several opened GitHub pull requests, so we will keep you updated.

One more thing… QMK supports mini OLED displays connected over the I2C communication bus. All of our knobs have a four-pin female connector exactly for this purpose. This allows you to use the same yellow display as ANAVI Macro Pad 8 on ANAVI Knobs 3 and ANAVI Knob 1.
